Miller Electric upgrades MDX Series MIG Welding Guns

Miller Electric Mfg recently introduced new MDX Series MIG guns.

Designed with operator comfort in mind, these MIG guns feature a durable and ergonomic handle with a rubber overmolding for improved grip, the company said, while the addition of a ball and socket handle swivel reduces fatigue.

AccuLock Series consumables add to the performance of the gun, providing a flawless wire feed path. The front-loading liner locks in place (no need for set screws) and aligns concentrically with both the contact tip and power pin to optimize wire feeding. Error-proof liner trimming, with no measuring required, reduces burnbacks, bird-nesting and erratic arc caused by liners that are too short, minimizing downtime for troubleshooting or rework.

The MDX Series includes three models: MDX-100, MDX-250 and MDX-250 EZ-Select. These guns are all compatible with Miller AccuLock MDX Series consumables, and the MDX-250 and MDX-250 EZ-Select guns also are compatible with Bernard AccuLock S consumables. Both AccuLock Series feature tapered connections between the contact tip, gas diffuser and neck to maximize electrical conductivity for longer product life. Coarse thread on the contact tips speeds replacement by mating easily with the gas diffuser and lessens the risk of cross-threading.

Bernard AccuLock S Consumables are an upgrade intended to increase durability and consumable life when welding with MDX-250 or MDX-250 EZ-Select guns in heavier industrial environments. They also simplify consumable inventory for operations using a mix of Miller MDX and Bernard MIG Guns.

Miller offers conversion parts to retrofit older style Miller MIGmatic M-Series guns with AccuLock MDX and AccuLock S consumables. M-Series consumables will not be compatible on the new MDX Series MIG guns.
